Compare

Stauroneis kishinena differs from S. americana by having strongly curved and expanded proximal raphe ends. Stauroneis finlandia and S. ursamaioris have protracted ends and more closely spaced striae. Stauroneis javanica, a fossil species from the Southern Hemisphere, has somewhat narrower valves (< 30 µm wide) and proximal raphe ends that are less strongly curved and expanded.
